About TPPP

Enables several functions, including magnesium ion binding activity; microtubule nucleator activity; and protein homodimerization activity. Involved in several processes, including microtubule cytoskeleton organization; negative regulation of tubulin deacetylation; and positive regulation of protein polymerization. Located in several cellular components, including cytoskeleton; mitochondrion; and perinuclear region of cytoplasm. Is active in Golgi apparatus. [provided by Alliance of Genome Resources, Apr 2025]
